I actually bought a tacklife drill from amazon and after a few months the plastic storage box clip broke. I was trying to fix that and designed this simple clip. It is my first design. I had to print it by elongating it on the length side by 110% instead of 100. Might be my printer setting or maybe the part is a bit smaller.

Increase the length (in my case only z axis) to 110% if the item is a bit tight. Ideally print with PETG for strength and flexibility. I used PLA though.
